TabBarButton is a button that is placed in the TabBar widget. It is a subclass of dojox/mobile/_ItemBase just like ListItem or IconItem. So, unlike Button, it has similar capability as ListItem or IconItem, such as icon support, transition, etc.


Constructor Parameters

Inherited from dojox/mobile/_ItemBase

Parameter Type Default Description
transition String “none” A type of animated transition effect. You can choose from the standard transition types, “slide”, “fade”, “flip”, or from the extended transition types, “cover”, “coverv”, “dissolve”, “reveal”, “revealv”, “scaleIn”, “scaleOut”, “slidev”, “swirl”, “zoomIn”, “zoomOut”, “cube”, and “swap”. If “none” is specified, transition occurs immediately without animation.
transitionDir Number 1 The transition direction. If 1, transition forward. If -1, transition backward. For example, the slide transition slides the view from right to left when dir == 1, and from left to right when dir == -1.
moveTo String “” The id of the transition destination view which resides in the current page. If the value has a hash sign (‘#’) before the id (e.g. #view1) and the dojo/hash module (=the dojox/mobile/bookmarkable module since V1.8) is loaded by the user application, the view transition updates the hash in the browser URL so that the user can bookmark the destination view. In this case, the user can also use the browser’s back/forward button to navigate through the views in the browser history. If null, transitions to a blank view. If ‘#’, returns to the previous view immediately without transition.
href String “” A URL of another web page to go to.
hrefTarget String “” A target that specifies where to open a page specified by href. The value will be passed to the 2nd argument of
url String “” A URL of an html fragment page or JSON data that represents a new view content (See examples below). The view content is loaded with XHR and inserted in the current page. Then a view transition occurs to the newly created view. The view is cached so that subsequent requests would not load the content again.
urlTarget String “” Node id under which a new view will be created according to the url parameter. If not specified, The new view will be created as a sibling of the current view.
callback Function String   A callback function that is called when the transition has been finished. A function reference, or name of a function in context.
sync Boolean true If true, XHR for the view content specified with the url parameter is performed synchronously. If false, it is done asynchronously and the progress indicator is displayed while loading the content. This parameter is effective only when the url parameter is used. In dojo-1.8, however, this property is no longer supported. It always behaves in the async manner regardless of the value of this property.
label String “” A label of the item. If the label is not specified, innerHTML is used as a label.
alt String “” An alt text for the icon image.
tabIndex String “0” Tabindex setting for the item so users can hit the tab key to focus on it.
